Defined Contribution Benefit Plan

13. Defined Contribution Benefit Plan

We maintain a defined contribution benefit plan under Section 401(k) of the Internal Revenue Code. Almost all of our domestic full-time employees are eligible to participate in this plan. Under the plan during 2011, we provided matching contributions of fifty cents for every dollar employees contribute up to a maximum of $3,000. During 2012, we provided matching contributions of fifty cents for every dollar employees contribute, up to the lesser of 3% of the employee's eligible compensation or $7,500. During 2013, we will provide matching contributions of fifty cents for every dollar employees contribute, up to the lesser of 3% of the employee's eligible compensation or $7,650.Generally, the plan calls for vesting of Company contributions over the initial five years of a participant's employment. We maintain a similar type of contribution plan at one of our foreign subsidiaries. Our contributions to these plans in 2012, 2011 and 2010 were $2.5 million, $2.1 million and $1.7 million, respectively.
